5-Axis CNC Machining Impeller

Employing 5-axis CNC machining presents a superior solution for fabricating intricate surfaces and irregular components, particularly those characterized by specific mathematical equations and demanding high precision, such as the complex vanes of an impeller.

A 5-axis CNC machine can maneuver the cutting tool along five distinct axes: X, Y, Z, and two additional rotational axes denoted as A and B. This empowers the machine to approach the workpiece from various angles and orientations, particularly advantageous when working with intricate and contoured shapes like impellers. This method offers enhanced flexibility, efficiency, and precision in making complex impeller geometries compared to traditional 3-axis machining since most, if not all, of the work can be completed in a single setup, eliminating the need for delays associated with part loading and unloading by an operator and reducing human errors significantly.

5-axis CNC machines facilitate more precise fabrication of impellers. Our rapid turnaround time, combined with consistent accuracy, streamlines the production of even the most precision-critical components. What may be deemed unachievable at other impeller machining facilities is standard practice for Runsom Precision.

Precision CNC milling impeller

Impeller CNC Machining Process

The impeller functions as a rotating component within a centrifugal pump, transferring energy from the pump's driving motor to the fluid being pumped by displacing it from the central rotation point. Typically made of metal, the impeller blades often feature complex curves and are closely packed, necessitating the use of long yet sturdy tools and making the machining process quite challenging.

CNC machined impeller-3

In general, machining an impeller from a blank involves utilizing CNC turning and CNC milling to remove excess material between the blades, shape the rough contours of the impeller, and ultimately refine the surface and blades. Modern computer-aided manufacturing (CAM) systems enable precise milling of the excess material in controlled layers.

The primary challenge in machining impeller blades lies in their thin, contorted, and closely aligned nature. Using a tapered end ball cutter to smoothly cut the blades in a continuous motion can produce a polished finish and prevent undesired vibration. Furthermore, aligning the center axis of the tool with the cutting force can significantly minimize lateral pressure and vibration, leading to a notably extended tool lifespan.

Material Selection for Impeller Machining

The material for the impeller should have excellent comprehensive mechanical properties, necessitating high standards for room temperature and high temperature strength, plasticity, and toughness. Therefore, the impeller material requires:

High vibration dampening capacity

Superior structural stability

Effective resistance to corrosion and erosion

Exceptional process performance

Adequate mechanical properties at high temperatures

As the impeller stands as a crucial component of the aero engine, it necessitates materials that minimize part weight while ensuring adequate strength. The selection of LD5 aluminum alloy grades is based on considerations of part usability and manufacturability.

The materials ideal for the overall impeller disc and blades include aluminum alloy, stainless steel, steel, titanium alloy, superalloy, and other composite materials. A comprehensive assessment of multiple factors such as working temperature, strength, state, and weight is necessary when determining the most suitable material.

CNC Machining Process for Impellers

The process of machining impellers involves multiple stages to produce a precise and effective part. Below is a general outline of the impeller machining process:

1. Design and Modeling

Commencing with the utilization of computer-aided design (CAD) software, the process entails the creation of a 3D model of the impeller. Engineers define the impeller's dimensions, blade profiles, and other essential attributes.

2. Material Selection

Impellers are commonly crafted from materials such as stainless steel, aluminum, bronze, or various alloys based on the intended application. The selection of material is based on factors like strength, corrosion resistance, and temperature endurance.

3. Material Preparation

The selected material is fashioned into a suitable form for machining. This may involve techniques like casting or other metalworking methods to generate a preliminary shape closely resembling the final impeller.

4. CNC Machining

The rough pre-formed impeller is inserted into the CNC machine, which utilizes a cutting tool to eliminate excess material and shape the impeller's blades, hub, and other characteristics.

5. Balancing

Achieving balance is a pivotal stage in impeller production to mitigate vibrations and ensure smooth operation. Following the machining process, the impeller undergoes balance verification, and in some cases, additional material may be removed from specific areas to attain the desired balance.

6. Finishing

Impellers may undergo supplementary finishing procedures such as polishing, deburring, and surface treatments to enhance their efficiency and longevity, depending on the intended application.

7. Quality Control

Before the impeller is deemed fit for use, it undergoes thorough quality control assessments. These evaluations ascertain that the dimensions, tolerances, and balance align with the specified parameters.

8. Assembly

Upon passing quality control assessments, the impeller can be integrated into the relevant pump, turbine, or compressor as part of the larger system.
